Why can't I update? I have never been able to update Quicken since 2018.

I get this message every time, have never been able to update Quicken. I have Quickbooks in same computer. Still using version R36.45 Build error message below:
The process cannot access the file'C:\ProgramData\Quicken\Inet\Common/patch/quickenPatch\w2773\base\ScreenShare\Quicken.Screenshare.exe'because it being used by another process.
